CME Course: Assessment of Stromal Tumor-Infiltrating Lymphocytes
The “Knowledge-based” course materials listed here are the same as those in the CME course. However, credit is only granted through the FDA CE Portal.
- The course is approved for 3.00 CME credits.
- Instructions for course access:
- Create an account in the FDA CE portal
- Click on “Online Learning” tab
- Scroll down to our course: “Assessment of Stromal Tumor-Infiltrating Lymphocytes”
- You can also use the search function on the “Online Learning” page to search for “Assessment”.
Description
Tumor-infiltrating lymphocytes have been established as a prognostic biomarker in early-stage triple negative breast cancer. The assessment of the density of stromal tumor-infiltrating lymphocytes at the time of diagnosis may improve the accuracy of prognosis determination and inform therapeutic decision-making.
Learning Objectives
After completing the module, the participant should be able to:
- Describe the significance of stromal tumor infiltrating lymphocytes in triple negative breast cancer.
- Demonstrate knowledge of the approach to determining the density of stromal tumor infiltrating lymphocytes.
Target Audience
Physicians
Course Content (3.00 CME credits)
1. Introduction to stromal tumor-infiltrating lymphocytes (12min presentation)
- We discuss the immune systems’ role in mediating tumor progression, and the statistics and literature that demonstrate how sTILs are prognostic biomarkers for patient outcomes and response to therapy in certain types of breast cancer.
- Watch the video here
2. TILs Education: What are TILs and their Assessment (8min tutorial video)
- Video description of the steps of the sTILs assessment.
- Presented by the International TILs Working Group
3. Pitfalls in the sTILs Assessment (27min presentation)
- Discussion of example pitfalls encountered in the sTILs assessment.
